Added a fancy SimpleModelProgressDialog!
Generated an actual Javadoc for the project!
Refactored the Image export/import classes.

Changes include extracting the image exporters/importers out of the
ImageExporter/ImageLoader classes, since it is a giant mess to look into
that class. Now, with all exporters/importers in their own classes,
order is restored and everyone can continue writing IO-code without
getting insane over the mess that we all produce!
Created a 'compressed' (Z)BIN image exporter.
Fixed a FATAL bug in the TGA exporter!

The image was flipped on the Y-axis! I hope no one used this exporter
until now!
Added MemoryWatcher component to Infobar!
Added progress dialogs to some of the exporters.
Added some Icons!

Tell me if you like them, change them to your liking if you don't like
them!
More Icons! And more Image Ops!
(added a note and corrected a tiny mistake)
More ImageOp's!
(updated javadoc)
(Added a nice little note to the main class!)
